Abstract

Soil and water conservation efforts continue to be encouraged, considering the increasing number of openings of oil palm plantations that occur in various regions, including Wawolemo Village Konawe Regency. Clearing new land for oil palm planting is generally carried out by land clearing, which has the potential to cause erosion, so soil and water conservation efforts are needed to prevent land degradation, especially the loss of nutrients in the topsoil layer due to erosion. This community service activity aims to provide the community in Wawolemo Village with an understanding of the importance of soil and water conservation. Activities carried out in January 2024 for the farmers/community of Wawolemo Village. The method used was in the form of lectures or counseling and evaluation, where questionnaires were filled out before and after the activity took place. The results of the activity showed that there was an increase in the understanding and insight of the Wawolemo Village community after being provided with education, especially about erosion, soil, and water conservation techniques, as well as environmentally friendly and sustainable palm oil plantation practices based on soil and water conservation. By implementing a soil and water conservation system, smallholder oil palm growers are also expected to be able to save on fertilizer costs, which have been considered quite large, in order to obtain optimal production. Upaya konservasi tanah dan air terus digalakkan mengingat semakin banyaknya pembukaan kebun kelapa sawit yang terjadi di berbagai daerah, tidak terkecuali Desa Wawolemo Kabupaten Konawe. Pembukaan lahan baru untuk penanaman kelapa sawit umumnya dilakukan dengan cara land clearing yang berpotensi menyebabkan erosi, sehingga diperlukan upaya konservasi tanah dan air untuk mencegah terjadinya degradasi lahan terutama hilangnya unsur hara pada lapisan tanah atas karena erosi. Kegiatan pengabdian kepada masyarakat ini bertujuan memberikan pemahaman kepada masyarakat di Desa Wawolemo tentang pentingnya konservasi tanah dan air. Kegiatan dilakukan pada bulan Januari 2024 pada petani/masayarakat Desa Wawolemo. Metode yang digunakan berupa ceramah atau penyuluhan dan evaluasi dengan mengisi kuesioner sebelum dan sesudah kegiatan berlangsung. Hasil kegiatan menunjukkan terjadi peningkatan pemahaman dan wawasan masyarakat Desa Wawolemo setelah diberikan penyuluhan terutama tentang erosi, teknik konservasi tanah dan air, serta praktik perkebunan kelapa sawit yang ramah lingkungan dan berkelanjutan berbasis konservasi tanah dan air. Dengan penerapan sistem konservasi tanah dan air, pekebun sawit rakyat juga diharapkan dapat berhemat dari biaya pemupukan yang selama ini dianggap cukup besar untuk mendapatkan produksi yang optimal.

Abstract

People's cocoa plantations in Padangguni District are generally located in a steep slope topographic condition with this condition the potential for erosion is very high which can affect land productivity in the community cocoa plantation area. The purpose of this research is to predict the actual erosion rate, determine the erosion hazard index classes, and recommend soil conservation alternatives on different slopes in smallholder cocoa plantations in Padangguni Sub-District, Konawe District. This research was conducted from October to December 2022 in Padangguni Sub-District, Konawe District. The survey method was used in this research, and the prediction of erosion rates was conducted using the USLE method on 3 land units: land unit 1 located in smallholder cocoa plantations with a slope of 6% covering an area of 14.6 ha, land unit 2 with a slope of 24% covering an area of 17.2 ha, and land unit 3 with a slope of 22% covering an area of 60.5 ha. The research results showed that the highest actual erosion occurred in land unit 3 at 1,307.74 tons/ha/year, while the lowest erosion occurred in land unit 1 at 1.12 tons/ha/year. The tolerated erosion rates were 31.61 tons/ha/year for land unit 1, 25.70 tons/ha/year for land unit 2, and 26.95 tons/ha/year for land unit 3. The highest erosion hazard index was found in land unit 3 at 48.52 tons/ha/year with a very high criteria, while the lowest erosion hazard index was found in land unit 1 at 0.04 tons/ha/year with a low criteria. The recommended soil conservation techniques to ensure the sustainability of smallholder cocoa plantations include applying vegetative conservation techniques using plant residues as mulch and mechanical methods through the construction of traditional terraces or roraks. Both scenarios of soil conservation action methods can reduce the actual erosion rate, making them appropriate choices for reducing erosion rates on cocoa plantation lands

Abstract

Soil quality is the ability of the soil to function to maintain plant productivity, maintain and maintain water availability and support human activities. The purpose of this study was to determine the Soil Quality Index (SQI) and determine the management direction for improving soil quality on different land uses in the Maginti sub-district. A field study and laboratory analysis were carried out from March to May 2022. The method used in this study was a free survey method through field observations conducted on 2 types of land use, namely irrigated rice fields and dry land. In irrigated rice fields, 3 sample points were taken and 3 sample points in dry land, then composited into 1 sample in order to represent the total amount of each land use. In calculating the value of the soil quality index using the formula by Bajracharya (2006) which has been modified by Ghimire (2018). The soil quality index is analyzed using the indicators that best represent soil functions. The variables observed included Texture, pH, C-Organic, N-Total, P-Available and K-Available. Soil quality index values range from 0-1, the higher the index value, the better the quality. The results of the analysis of the selected soil functions (minimum data set/MDS) and the MDS scoring were summed to determine the value of the soil quality index (SQI). The conclusion of this research is that the criteria for medium soil quality are irrigated rice fields with SQI (0,56) and dry land with low criteria with SQI (0,36). To improve soil quality in irrigated paddy fields and dry lands is to increase organic matter through the application of organic fertilizers with the right dosage according to the type and level of soil fertility.Keywords: Soil Quality Index, Irrigated Rice Fields, Non-Irrigation, Soil Management, Physical Properties of Soil Chemistry.
